I have had my BGK for three years. He is over 14 inches long now. All his life, I have fed him bloodworms and beefheart. I run the beefheart through a food processor and chop it up finely. I also have discus and angels and a few other assorted fish in with him and ALL of them like the beefheart as well. I feed only
at night. What I do, is put the food in the tank, wait 5 minutes then shut the lights off, this way he will come out and eat without being annoyed by the light.
